I've run into the same issue. I bought 2 ORA Lightning Maroons through Live Aqauaria for our 50 gallon anemone tank. They were fine for the first 2 or 3 days but then they started fighting and lip locking. The smaller of the 2 was actually the aggressor. I put the aggressive one in an acclimation box for 2 weeks hoping that it would give the other one an opportunity to claim a territory and heal up a bit. Once I let the smaller one out of the box after about a day they were back at it again. By the time I was able to get the larger clown out of the tank and into a quarantine tank it was too late. It only lasted a day before it died. I've contacted ORA hoping they might have some advice as to how I might be able to introduce another Lightning Maroon into this tank without ending up in the same situation again.
